I used to believe until I started questioning verses and their meaning like this one. no one can answer without clear indoctrination.

“For the Son of Man is going to come in the glory of His Father with His angels, and will then repay every man according to his deeds. Truly I say to you, there are some of those who are standing here who will not taste death until they see the Son of Man coming in His kingdom.“ (Matthew 16: 27, 28)
